T 0 all whom it may concern..-

Be it known that I, EMIL J. Knicis, a citizen of the United States, anda resident of the city of Mendota; county of Lasalle, and State ofIllinois, have invented certain new and useful Improvements in ResilientWheels, of which the following is a specification.

My invention relates to improvements in resilient wheels and has for itsobject the provision of a wheel of this character which shall be ofsimple construction and etiicient in operation.

A further and particular object of my invention is to provide aresilient device which may be attached to an ordinary wheel having aclencher rim, in the same manner as a pneumatic tire.

The invention consists in the combinations scribed and claimed.

The invention will be best understood by reference to the accompanyingdrawing forming a part of this specification, and in which,

Figure 1 is a partial elevation of the rim of a wheel embodying myinvention, aportion of said rim being broken away and shown in section,and Fig. 2 an enlarged section through the rim of the wheel.

The preferred form of construction as illustrated in the drawingscoiiprises an ordinary wheel of any desired cthystruction and providedwith an ordinary split rim 1 having the usual securing flange as shown.A supporting member 3cons ting of an annular channel member having si es1 is secured in position on rim 1 by means of .beads 5 provided at itsinner edges and held in position by securing flanges 2, as indicated.Metallic guard rings 6 are placed at either side of supporting member 3and held in position by means of beads 7 engaging securing flanges 2 asshown.

A tread member 8 is provided with a solid rubber tread 9 and carriesinwardly extending leather rings 10 having reinforcing metallic rings 11secured to their inner edges and fitting loosely between the guard rings6 and the sides 1 of supporting member 3. By this construction the treadmember is formed into an annular channel member radially movable withrespect to the supporting member Threaded studs 12 having circularsecuring heads 13 are secured at suitable intervals to the inner side ofthe bottom of tread member 8 by means of a ring 14 which is perforatedto permit the passage of studs 1'2 and is provided with recesses adaptedtpo receive the heads 13. This ring is securel in position by means ofrivets 11' and studs 12 are further secured in position by means ofrivets 13 passing through ring 1% and heads 13. Bolts 15 are secured instuds'12 and project inwardly through circumferentially elongated slots16 in he bottom'ott' supporting member 3 as shown. Rocker supports 17are provided at each side of studs 12 and support the outer ends ofsprings 18 on bolts 15 and bearing againstthe outer side of the bot-tomof supporting member Springs 19 are interposed between the inner sidesof the bottom of supporting member 3 and the heads '20 of bolts 15. Bythis construction it will be observed that the weight on the axle of thewheel will be resilient supported by the springs 18, in

the lower portion of the wheel and by the springs 19 in the upperportion of the wheel. The rocker supports 17 and the circumferentialslots 16 permit of the necessary movements of springs 18 and bolts 15 inadjusting themselves to proper positions as the wheel rotates.

\Vhile I have illustrated and described the preferred form ofconstruction for carrying my invention into effect, this is capable ofvariation and modification'without departing from the spirit of theinvention. I. therefore. do notwish to be limited to the exact detailsof construction set forth, but desire to avail myself of such variationsnd modifications as come within the scope of the appended claims.

Having described my invention what I claim as new and desire to secureby Letters Patent is:

1. In a device of the class described. a supporting member consisting ofan annular channel memberprovided with heads at its edges adapted toengage the flanges of a clencher rim, there being slots in the bottom ofsaid channel member; a tread member consisting of an annular channelmcmber loosely enga ing said supporting member; bolts secured to saidtread member and projecting through said slots; springs on said boltsinterposed between said tread and outer side of the bottom of saidsupporting of said supporting member and the headsof said bolts,substantially as described.
